Inputs

Geometry

Connect the geometry from which polygons should be detached here.

Selection

Here you can assign the indices of the polygons, edge points or points to the Node that should be detached. If you would like to access an already saved selection or an active selection, for example, you can also use the Selection string as an alternative. You define whether the indices should be related to points, edges or polygons in the Mode setting.

Mode

Here you choose whether the specific selection should be applied to the points, edges or polygons of the geometry. When defining a point or edge selection, note that all points or edges of a polygon must be selected for the corresponding polygon to be detached.

Selection String

Here you can, for example, use the name of a selection in quotation marks that you want to read out, e.g., "MySelection". Otherwise, the default entry will use an active selection on the geometry.

You can also use special keywords and logical operations here to create a new selection from scratch or a combination of already saved selections. The following keywords and operations can be used:

  • Default: This term causes an active selection currently present on the geometry to be used. If no selection is active, all points will be used.
  • odd: This term is used to select all elements that have an odd index number.
  • even: This term is used to select all elements that have an even index number.
  • all: This selects all elements of the selected type.
  • hidden: Selects the hidden elements of the geometry.
  • Name of a saved selection: If you enter the name of a saved selection in quotation marks, this selection will be read and used. To use a combination of a saved selection and another keyword or selection, use quotation marks with the selection name.
  • Index numbers: You can also use index numbers directly, just as you are used to from the Index Array From String Node.
  • Mathematical and logical operations: Mathematical or logical operations can be used to combine selections. Using the string odd – "center" for instance selects all odd elements and then subtracts the selection that has been stored by the name "center". You can use +, -, & (logical and), | (logical or) as well as a comma to combine multiple selections or index sequences.

Preserve Groups

If this option is activated, the neighboring detached polygons remain connected. Otherwise, each selected polygon is replaced separately. The number of points is then even higher and each polygon can be manipulated independently of its neighbors. However, this also interrupts the phong shading on all polygon edges.
